iPhone Dev team has just released a new version of Redsn0w – Redsn0w 0.9.10b1, which finally allows iPhone 4 GSM, iPhone 4 CDMA and iPhone 3GS users to perform an untethered jailbreak.

In this guide, we will take you through the step by step procedure to jailbreak iPhone running iOS 5.0.1 without updating the baseband using Redsn0w.

Here are some important points to note before you proceed.

This guide is meant for iPhone 4 and iPhone 3GS users who are interested in unlocking their iPhone using Ultrasn0w – a software method. iPod touch 4G and iPod touch 3G users can checkout this guide, while iPad users can checkout this guide.

If you don’t care about unlocking your iPhone and/or preserving the baseband then checkout this step-by-step guide.

It is always a good idea to take a backup of SHSH blobs using TinyUmbrella (Windows and Mac) or iFaith before upgrading to iOS 5.0.1 so you can downgrade to the current version if required.

Please do not forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.

If you’ve jailbroken your iPhone then you can use jailbreak apps such as AptBackup, PkgBackup or xBackup from Cydia to take a backup of all the jailbreak apps and tweaks so you can reinstall them easily after successfully jailbreaking your iPhone rather then installing them individually. However, since you’re moving from iOS 4.x to iOS 5, it may be a good idea to reinstall the jailbreak apps to avoid compatibility issues.

Please ensure you are running latest version of iTunes i.e. iTunes 10.5 or later.

Update: Some readers are reporting issue with iBooks after jailbreaking their iPhone.

You can follow these step-by-step instructions to jailbreak your iPhone 4 and iPhone 3GS:Step 1: Download Redsn0w 0.9.10b1 for Windows from this link and Redsn0w 0.9.10b1 for Mac from this link and save the application in a folder named “Redsn0w” on your desktop.

Step 2: You need to download the iOS 5.0.1 firmware file (use Firefox or Chrome to download the firmware file instead of using Internet Explorer or Safari):

Step 10: Once the custom iOS 5 firmware file is successfully created, you will be notified with a dialogue box. Click on the Ok button to continue. You will notice that Redsn0w has created the custom iOS 5.0.1 firmware file with a prefix “NO_BB_”. So custom iOS 5 firmware file for iPhone 4 will be NO_BB_iPhone3,1_5.0.1_9A405_Restore.ipsw and for iPhone 3GS it will beNO_BB_iPhone2,1_5.0.1_9A405_Restore.ipsw.

Step 11: You will now need to put your iPhone into the DFU mode. Redsn0w will take you through the necessary steps:

(a) Hold the Power button on iPhone down for 3 seconds:

(b) Now simultaneously hold the iPhone and keep the two buttons pressed for 10 seconds:

(c) Now release the Power button while keeping the Home button pressed until Redsn0w detects the device:

Step 12: Redsn0w will run the Limera1n exploit.

Step 13: You will be notified when your iPhone is in Pwned DFU mode. The Pwned DFU will allow you to restore your iPhone using the custom iOS 5 firmware file.

Step 14: Now launch iTunes.

Step 15: From the ‘Devices‘ section on the left pane of iTunes, select your iPhone. Now, hold down the Option button (or Shift button for Windows) and click the ‘Restore‘ button.

Important Note: It is very important that you hold down the Option button (or Shift button for Windows) else you will end up accidentally upgrading your iPhone to iOS 5, so please follow the instructions carefully.

Step 16: Navigate to the Redsn0w folder on the desktop and select the downloaded iOS 5 firmware file (iPhone 4 users – please select NO_BB_iPhone3,1_5.0.1_9A405_Restore.ipsw and iPhone 3GS users – please select NO_BB_iPhone2,1_5.0.1_9A405_Restore.ipsw). Click on the ‘Choose‘ button to let iTunes update your iPhone with the jailbroken custom iOS 5 firmware. You will be asked to setup your iPhone either from a previous backup or setup as a new iPhone, select the backup you want for your device (ideally should be the most recent one). Wait for iTunes to finish.

After this, you need to follow the instructions in our step-by-step guide to jailbreak your iPhone on iOS 5.0.1.

If you’re new to the jailbreaking world and wondering what to do after jailbreaking your iPhone, checkout our jailbreak apps category page to find out the apps you can install on your iPhone using the Cydia app. Please note that some of the jailbreak apps and tweaks are still not compatible with iOS 5/iOS 5.0.1 so please be cautious while installing them.

After weeks of anticipation, the iOS 5.0.1 untethered jailbreak is finally here, compliments of pod2g, Chronic Dev Team, and the Dev Team. As we explained a little earlier today, you currently have two ways to untether.

Depending on your situation, you can either run the latest version of RedSn0w, or if you’re already jailbroken, you can use the Cydia package called Corona Untether 5.0.1 to do the job. This is what we’ll focus on in this post…

We realize there isn’t much to Corona Untether 5.0.1. It’s fairly easy and straightforward, but to make things very clear and simple for everyone, we thought we’d have a dedicated post for it.

Who should use Corona Untether 5.0.1?

Anyone running a tethered jailbreak for iOS 5.0.1 may use this Cydia package to untether. That means that if your device is running iOS 5.0.1, and that you have a tethered jailbreak, then Corona Untether 5.0.1 is for you. Supported devices include the iPhone 3GS, iPhone 4, iPhone 4 CDMA, iPad 1, iPod touch 3G, and iPod touch 4G.

How to untether?

Because you’re already running a jailbroken version of iOS 5.0.1, the untether process is going to be fairly easy for you.

Step 1: Launch Cydia and search for Corona Untether 5.0.1.

Step 2: Tap “Install” and let Cydia do the rest of the job for you.

That’s all there is to it. You can now safely reboot your iPhone, iPod, or iPad without the need of an external tool such as RedSn0w to boot tether.
